A new double toothedrollcrusher was studied base on the traditional crashers, and its work mechanism, structure and technique characteristics were introduced.
In addition, according to the crushing strength and physical, chemical properties of manganese nodule, the testing method for crushing using toothedrollcrusher is established.
同时根据锰结核的破碎强度和物理化学特性确定了用齿辊破碎方式进行破碎的实验方法。
